IT maintenance must guarantee the availability of applications<\/strong>, as well as the long-term performance of the IT equipment. It is therefore organised into 3 categories of maintenance: preventive, corrective and evolutionary.<\/p>\n<\/div>\n\n\n
1 \/ Preventive maintenance<\/strong><\/p>\n<\/div>\n\n\n
Preventive computer maintenance consists of avoiding the appearance of problems. It can concern the computer security of the park<\/strong>, but also the improvement of its performance. Preventive interventions can be organised on a more or less regular basis, depending on needs. <\/p>\n<\/div>\n\n\n
This type of computer maintenance therefore concerns both antivirus software and software updates. It also includes firewall management, temporary file cleaning and hard disk defragmentation.<\/p>\n<\/div>\n\n
\n
Preventive maintenance<\/strong> also concerns hardware. As part of a preventive intervention, a technician can revise the equipment, clean it, make improvements to the settings to change parts likely to cause breakdowns in advance.<\/p>\n<\/div>\n\n\n
2 \/ Corrective maintenance<\/strong><\/p>\n<\/div>\n\n\n
Carrying out corrective or curative maintenance<\/strong> means repairing equipment or software. These are one-off operations carried out when the equipment is no longer working or when it is subject to a computer virus. Corrective maintenance of information equipment takes two forms:<\/p>\n<\/div>\n\n\n\n- palliative maintenance<\/strong>: the IT maintenance provider carries out a temporary repair of the damage. Objective: to maintain the operation of the IS in the short term, to ensure the continuity of the company’s activities;<\/li>\n<\/ul>\n\n\n\n
\n- curative IT maintenance<\/strong>: repairing the faulty equipment so that it returns to its initial state.<\/li>\n<\/ul>\n\n\n
\n
3 \/ “Evolutionary” maintenance<\/strong><\/p>\n<\/div>\n\n\n
Evolutionary maintenance <\/strong>consists of supporting the computer equipment <\/strong>over time. It may involve offering new hardware or software tools to users, based on the latest technological developments. Evolutionary maintenance also includes system updates and upgrades of the computer equipment<\/strong>.<\/p>\n<\/div>\n\n\n
3 levels of maintenance depending on the complexity of the IT problem<\/h2>\n<\/div>\n\n\n
When a company outsources its IT maintenance<\/strong>, it can benefit from different levels of user support. A user who contacts the helpdesk of the service provider company exchanges with technicians. These technicians are responsible for :<\/p>\n<\/div>\n\n\n\n- identify the problem;<\/li>\n<\/ul>\n\n\n\n
\n- classify it according to a level of seriousness<\/li>\n<\/ul>\n\n\n\n
\n- open a “helpdesk ticket” describing the problem<\/li>\n<\/ul>\n\n\n\n
\n- draw up a list of actions to be taken to “close the ticket”, i.e. resolve the customer’s problem.<\/li>\n<\/ul>\n\n\n
\n
The second step, which consists of classifying the problem by degree of seriousness, leads in fact to prioritise the ticket according to 3 levels of maintenance:<\/p>\n<\/div>\n\n\n
\n- The first level refers to “easy” IT maintenance<\/strong>. This may involve, for example, providing remote assistance to a user who is unable to use a software package. First-level maintenance covers basic faults that do not need to be escalated.<\/li>\n<\/ul>\n\n\n\n
\n- Level 2 IT maintenance concerns incidents that block the user and require further technical exploration<\/strong>. Technicians may need to contact software suppliers or equipment manufacturers. Generally, this type of problem cannot be resolved remotely. It involves a return to the workshop for testing and a full technical diagnosis. The team of technicians involved has a more in-depth knowledge of the various IT environments.<\/li>\n<\/ul>\n\n\n\n
\n- Level 3 IT support is deployed either on site or in the workshop. It concerns a critical incident for the client company<\/strong>, likely to threaten the continuity of its activities. This is an emergency, handled by experts. A replacement of the out-of-service equipment can be organised by sending a functional equipment on site and collecting the out-of-service equipment.<\/li>\n<\/ul>\n\n\n
\n
What is the difference between IT maintenance and outsourcing?<\/h2>\n<\/div>\n\n\n
The difference between IT maintenance and outsourcing<\/strong> generally lies in the type of technical personnel involved. The word “maintenance” can sometimes be used to designate the activities of a company’s internal IT department. In this case, the latter is responsible for restoring the equipment to its original condition without the intervention of a third party.<\/p>\n<\/div>\n\n\n
Managed services” refers to the outsourcing of all or part of the company’s IT department<\/strong>. The company thus delegates the management of its equipment to a service provider<\/strong>. The latter then takes charge of all types of IT maintenance. It also offers all the levels of support detailed above, all within a commitment contract. In practice, a facilities management service can therefore include IS maintenance.<\/p>\n<\/div>\n\n
